Rules rile champion Bolt
Usain Bolt said the London Olympics have been "great" but that he has been riled by petty rules.
The Jamaican, speaking after winning the 100m in an Olympic record, said he really enjoyed being at the athletes village but chafed at the red tape.
He told a news conference: "There are a lot of rules, oh my God. You can't do anything.
"I was coming and wanted to bring my tablets in and they said I couldn't. I asked why. It is just a rule.
"I had my skipping rope in my bag and they said I can't bring it in. Why? It is just a rule.
"What if I need to take a rubber band inside to stretch? I can't take it inside because it is a rule. It is just very small rules that don't make any sense to me."
Bolt said he even encountered the rules at the start of the 100m.
He added: "The guy was telling us to line up. We were about to race and we were being told to stand in a straight line. It is kind of weird."
Earlier, he told reporters: "Great Britain is a wonderful place. They've done so well, I've been watching the cycling and the rowing, they've done so well. It's just a great Olympics, it's just a great place."
He also said that he was enjoying life inside the athletes' village however and had been playing video games.
Bolt added he will be aiming to make it a 100m treble at the Rio de Janeiro Olympics in four years' time.
He added: "I'll be 30 but I hope I'll be there."
